■DICOM (Digital input I/F power supply)
Input 24 V DC (24 V DC ± 10 %, 300 mA) for I/O interfaces. The power supply capacity varies depending on the number of I/
O interface points to be used.
For sink interfaces, connect the positive terminal of the 24 V DC external power supply.
For source interfaces, connect the negative terminal of the 24 V DC external power supply.
■DOCOM (Digital output I/F power supply)
Input 24 V DC (24 V DC ± 10 %, 300 mA) for I/O interfaces. The power supply capacity varies depending on the number of I/
O interface points to be used.
For sink interfaces, connect the negative terminal of the 24 V DC external power supply.
For source interfaces, connect the positive terminal of the 24 V DC external power supply.
■SD (Shield)
